Do Plecos need caves?

By James White |

Do Plecos need caves?

A barren tank will stress your fish and make it shy and bored. Plecos need hiding spots throughout the tank where they can stay during the day because they're nocturnal. Hiding spots can be created using all sorts of aquarium decorations like caves, tunnels, dark pipes, wood, and artificial plants.

Also to know is, do all Plecos need driftwood?

Most species of pleco sold today actually eat the driftwood, so yes, it's a necessity for them. They need it for healthy digestion.

One may also ask, can Plecos live without oxygen? They should be fine. Air is not essential for most fish, though oxygen levels in the water need to be adequate. So long as the water is circulating freely and there is air over it so that gas exchange can take place, most tanks have plenty of oxygen for most fish.

Furthermore, do Plecos really clean your tank?

A visit to the fish store reveals an entire world of algae eaters. Pleco does a great job of eating the algae in the tank, too. But two weeks later, he's dead. If you've got a good store, they explain to you that you do actually need to feed your pleco, sell you another and a bag of algae wafers.

Do Plecos need to be in pairs?

"No" to Multiple Plecos Together

They can be highly territorial around each other. Therefore, it can be extremely dangerous ever to house them together. When they're alone and away from other plecos, they can make serene and pleasant community tank inhabitants, however.

What kind of driftwood do Plecos like?

As long as it's wood specifically for aquariums (usually driftwood) it's fine. Malaysian driftwood is the best. Mopani is too hard, grape vines (sold in pet stores for reptiles) mess up the tank, spider wood and manzanita is lacking the width to provide hiding spaces.

What kind of food do Plecos eat?

Does a pleco need a heater?

You could go with 2 females and they should get along. I don't recommend you put 2 males in there though. They can get territorial. I usually don't recommend them for algae control though.

Are Plecos dirty fish?

Plecos are messy fish which produce a lot of waste (and no, they don't eat poop). They requre heavy filtration and lots of water changes. Having a pleco is NOT a substitute for regularly cleaning your tank, doing water changes and vacuuming your substrate to remove waste.

Why do Plecos poop so much?

Firstly, a lot of the dreaded pleco poop comes from eaten algae, which you cannot really control beyond reducing light, which you can't do in a planted tank. Secondly, in most tanks you can't really control how much each individual fish eats. You feed them as a group.

Why is my Plecos poop so long?

If they aren't passing a lot of feces, they aren't being fed enough. Plecos need to eat a lot, and feeding every 3 days is really bad advice. Any fish that eats vegetable matter needs a lot of food volume. If they aren't passing a lot of feces, they aren't being fed enough.

How big will a pleco get in a 10 gallon tank?

Some plecs stay small 8 inches or so, others grow to 12 inches or more. These guys need around 200 litres as a minimum for them to be happy, and yes they do create a lot of waste matter, the filter on a small 10g tank may not cope.

Why do Plecos die?

There are lots of reasons why this happened. Primarily though, I'd say your pleco died of a combination of being too cold and being in an un cycled aquarium. Look up the nitrogen cycle and fishless and fish-in cycling on this website. Also, never, ever take the fish out of the tank for any reason.

Do shrimps eat poop?

In a well matured tank bio film will breakdown "eat" fish poop and in turn your shrimp will graze on the bio film, but as stated above they do not feed on feces itself. Ghost shrimp are usually sold as feeders in LFS so I'd say go for a dozen or so, not just one.

Can Plecos survive without a filter?
